Oklo Resources reveals positive initial test work results from Dandoko Project in Mali

The results strongly indicate that the use of cyanide leach is appropriate at this early stage of testing.

Oklo Resources Ltd (ASX:OKU) has received excellent results from preliminary metallurgical test work completed on samples collected from the Seko prospect at its Dandoko Project in Mali.

The preliminary results from bottle roll cyanide leach analysis on oxide and primary mineralisation samples provide a positive indication on the likely recovery characteristics of the ore.

Bottle roll cyanide leach analysis provides an initial indication of the recovery characteristics of an ore by comparison to the more conventional fire assay analysis.

Encouragingly, results from the bottle roll cyanide leach analysis returned an average difference on oxide and primary mineralisation of less than 5% (95% recovery) between the original fire assay and follow up bottle roll assays.

When broken down by material type, both primary and oxide samples returned excellent results.

The primary averaged less than 6% (94% recovery) difference and the oxide samples less than 2% (98% recovery) difference, strongly indicating that the use of cyanide leach is appropriate at this early stage of testing.


The bottle roll analysis was conducted prior to committing to an expanded metallurgical test program.

Further sampling of both oxide and primary material is now underway and will be submitted for test work.

Oklo managing director Simon Taylor said: “While this preliminary testing is only the first of an initial program of metallurgical work, these early results indicate an easily recoverable gold at Seko.

“The company is highly encouraged by these results and provided a catalyst for further metallurgical testing, we look forward to releasing the results as they become available.”
